Question

5. The energy that should be added to an electron to
reduce its De broglie wavelength from 10-10m to
0.5 x 10-10 m will be :​

Answer 1

Answer:

Thrice the initial energy

Explanation:

Let us consider the equation

         λ=h2mE

λ1λ2=E2E1

⇒ 1×10−90.5×10−9=E2E1

Answer 2

Answer:

Thrice the initial energy

Explanation:

Let us consider the equation
